摘　　要：对于贵州瓮安上震旦统含磷地层中产出的管柱状微体化石的主流认识,从古老海百合茎枝,转变为床板珊瑚实体化石。作者通过对该地层产出的大量管柱状化石电镜下分析以及形态结构对比研究,认为该类化石材料在形态结构上存在明显差异,这些管柱状微体化石可能具有多源性,应将其按形态进行系统形态分类后再讨论。The main interpretation of cylindrical and tabulate microtossils which preserved in Phospnatic sedimentary rocks of terminal Proterozoic in Guizhou province has been varied from miniature crinoid stems to extinct tabulates . Base on SEM studies of more than 50 specimens, the author found these tube fossils are not uniform in configuration and structure, they may have different nascence , so the author propose that they might should be classified in morphological .
